The regular Merida Speeder is a fast efficient commuting or leisure bike. The addition of a power unit is almost unnoticeable when the bike's seen in profile. The smooth power delivery and drag free motor help preserve your energy, making commuting far more appealing. MAHLE's ebikemotion system uses a 40Nm rear hub motor powered by a fully integrated 250Wh battery hidden in the downtube. The low system weight combined with a carbon fork and sophisticated aluminium frame means the bike also feels lively without power assistance. There is almost no drag at all from the motor when it's not engaged. The system has an iWoc button for controlling support levels and a sophisticated app provides an opportunity to adjust the riding feel as well as offering post-ride analysis features. Fully equipped with kickstand, mudguards, rack and Lezyne lights you are good to go in all weathers. Cable routing is through the frame with cables entering through a specific headset cap to keep the cockpit nice and neat.
